In Option 2 the users input the cross section as a closet-loop by points with (dx, dy) from the one to the next point as shown in examples below. The case of massive deck the family file can customize directly for use in Civil Structures.

For the box-girder the hole must be done manually before customization.  


 

 

Figure: Revit model for 11-bottom-lines, massive deck (top) and box-girder (bottom).


  

Once the 2D-Profile family for the box-girder customized in Civil Structures, the 3D bridge is automated as shown to right. See this page for the curved alignment of bridge with this cross section.

 

In addition, using ICDAS Revit Bridge Manual, the users can find more types of cross sections being used in Civil Structures, or to design concrete bridge manually as well.

Pier design


In Option 1 the pier is design in Generic Model family as the deck, then load both family files into project file for the bridge. In addition, the pier design in Option 1 can be loaded to the bridge project in Option 2 and 3 as well. Also, the pier design can be loaded as concrete pylon in cable-stayed bridge project file.

 

ICDAS creates 3D Pier by 12 inputs on top, and 12 inputs at bottom profile of the pier as shown to right. Set e.g. c1=c3=d1=d3=0 on both of top and bottom profile, one will get a rectangular pier. Set the top profile eccentric from the bottom, one will get an inclining pier either in bridge direction, or in cross direction.


By default, the input has two columns in a family file. If more that two columns needed, than design the pier dimensions so that it can be repeatable loaded in project file, or apply an additional new family file.

 

Pier design is in Excel sheet BRIDGE. The pier design has 7 rows input outlined in numerical example below.

The two columns are set eccentric 5000mm from the center to the left and right (EccL & EccR).

The sharp corners at the foundations bottom are due to (WidthT, WidthB)=(4500, 7000)mm have been set in input.

 

 

In the above input the values in grey color are not used for Concrete Bridge.


Below shows another example of pier where eccentric EccL=EccR=0 at the bottom which give a V-shape pier with two-columns.

The level on top of pier is set below bottom of bearing in ICDAS Pier family files. Thus, any pier in ICDAS library loaded in project will be fitted to the deck vertically, and automatically. The height of pier h3 is gen from top of pier to top of foundation.
